Question

The space between the lens and the cornea of the human eye is
A. Vitreous chamber
B. Anterior chamber
C. Retina
D. Iris

Answer 1

Hint: The eyeball contains a transparent lens which is held by ligaments further attached to the ciliary body. Lens divides the eyeball into two chambers: outer aqueous chamber and inner vitreous chamber. It is the front part of the eye.

Complete answer: The eyeball contains a transparent glass-like lens which is held in position by ligaments further attached to the ciliary body. These ligaments are called suspensory ligament or Zonula of Zinn. In front of the lens, the pupil is surrounded by iris. Muscle fibres of iris regulate the diameter of the pupil. It is an ectodermal, colourless, biconvex fibrous structure made up of proteins and enclosed in the lens membrane. Sometimes due to defective protein metabolism, the lens becomes opaque. This is called a cataract. The space between the lens and the cornea of the human eye is called the anterior chamber. Hyphema, anterior uveitis and glaucoma are three main pathologies in this area. The depth of the anterior chamber of the eye varies between 1.5 and 4.0 mm, averaging 3.0 mm. Due to the increase in intraocular pressure in the aqueous chamber, glaucoma is caused. Surgery may be required to open the blocked canal.
So, the correct answer is option B.

Additional information: Difference between aqueous humour and vitreous humour:

Aqueous humour	Vitreous humour
It occurs in the aqueous chamber.	It occurs in the vitreous chamber.
It is a transparent watery fluid.	It is a transparent jelly-like substance.
It is secreted by ciliary processes.	It is discharged by the retina during the development of the eye.
It is continuously absorbed into the blood and replaced.	It is not absorbed or replaced.
Obstruction in its stream may harm retina by expanding intraocular pressure.	It does not flow.

Note: Eyes are the organs of the visual system. Some of the common eye defects are myopia, hypermetropia, presbyopia and astigmatism. Myopia can be corrected by using convex lenses, hypermetropia can be corrected by using concave lenses, whereas astigmatism can be corrected by using cylindrical lenses.
